According to the California Department of Public Health several counties were lowered to less restrictive levels of the state’s monitoring system on Tuesday, Sept. 22.
Riverside County was the only Southern California county to move; it was lowered from the most restrictive purple tier to red. Once a county’s tier has changed it must remain there for three weeks.
A county must also meet criteria for the next tier in daily coronavirus positive cases per 100,000 and testing positivity for two consecutive weeks in order to progress down a level.
Modoc, Alpine and Maripossa counties are the only three of the state’s 58 counties to reach the minimal (yellow) level.
